A survey of fog computing: Privacy and security considerations

Because of the inherent limitations of Internet of Things (IoT) devices, such as limited storage and computing capacity, a new platform is required to handle data effectively. Fog computing is a technique that was developed to bridge the gap between distant data centers and IoT devices. Fog computing offers a number of advantages, including increased security, reduced bandwidth, and lower latency. Because of these advantages, fog is an ideal paradigm for many IoT services in a variety of applications, including linked cars and smart grids. Nonetheless, fog devices, like conventional data centers, are exposed to a variety of security and privacy risks. The authors of this paper address security and privacy concerns in IoT settings and suggest a fog-based method to optimize the dissemination of certificate revocation information across IoT devices for increased security. They also discuss possible research paths for utilizing fog computing to improve security and privacy in IoT settings.
